In this video, I’ll show you how I created a T-track and MDF spoilboard for my new Avid CNC 4848 Pro CNC Router! First I’ll show you how I laid out the t-track. I’ll then show you how I spaced the t-track using the MDF strips I’ll be attaching to the table top. Then I’ll show you how I mounted and sealed the MDF. And then I’ll show you the two toolpaths I created in Vectric Aspire to surface the spoilboard.
Finally, I’ll surface the MDF spoilboard to get it nice and flat.
As usual, if you have any comments or questions about anything I covered in this video, please join me for the Live Q&A, or put ‘em in the comment section below.

Best intro of all time! If you layout a pattern of holes on your MDO base, you could use 1/4x20 inserts and design a repeated pattern for each strip of MDF so you can easily remove and replace your spoilboards when they get too used up.
Probably, but I don't ever plan on replacing one of them. When I surface them down to the point that they're getting close to the top of the aluminum t-track, I'll just glue some 1/4 inch thick MDF on top of them, surface them flat, and drive on.
You are so kind and your explanations are very enlightening thank you for this lesson
Love how clean that dust boot leaves your table. Thanks for the support!
If you love it, imagine how I feel. This is GREAT Keith! Thank you!
Nice video Mark, love the spoil board setup and the DC is spot on with that boot!!!
Watching this build and getting to this point has been awesome! I can’t wait to see what projects come off this CNC!
Time for the pirate!!! Nice job
Looking good Mark. Now run some projects and chew up that spoil board. 😂
Good idea. A closer view would be helpful to get an idea of how this actually works.
Great vid mate.
I installed a very similar setup but used the CNC to cut slots for the track and their mounting holes. With those installed, I stuck up on the fit of the MDF slats.
Mark, why not just glue the whole board down and CNC mill the slot for the aluminum. MDF doesn't really need sealing but I would have used a thinned shellac.
There are a lot of ways to skin the proverbial cat. As long as you get the result you want, that's what counts. As far as sealing the MDF is concerned, I have to. I live in an area that gets dense fog for days at a time. If I don't seal the MDF, it will swell and eventually start to mildew and rot. It's happened to me before - that's how I know I need to seal it. As I said in the video, I normally would have used thinned shellac (or shellac-based sanding sealer,) but I was out of it and I needed to get it sealed ASAP.
Good morning Mark. That spoilboard looks really nice!! I'm really liking the t-track idea.👍
I have a question, didn't you find that the mdf was a little rough after you sealed it?
Did you lightly sand in between coats?
I used the polycrylic to seal my mdf cnc benchtop and it did not dry smooth. I had to sand between coats.
I've used the Sanding Sealer on mdf for other small projects and it works really good (but I think I still had to sand it). Probably should've used it for my benchtop. 🤷♂️😃
I won't be able to make your live stream today, so I figured I'd ask here.
Thanks a lot Mark!!
Thank you, Joe. Yes, the MDF is a little rough, but that's to be expected. It's nothing a little 220 grit on a sanding block won't cure in about one minute. I didn't sand between coats. I'm not going for a showroom finish - I'm just trying to keep the MDF from absorbing a ton of moisture over the winter.
@@MarkLindsayCNC Ok yeah, that makes sense. Thanks so much for getting back to me. 👍
So do you feel that the roughness will NOT affect your material or make it a little uneven in certain spots?
This is the 3rd spoilboard I've done this way, and I've never noticed any unevenness (is that a word? I guess it is now...) I do know that if I don't seal the MDF it WILL be uneven as heck before January. We get a lot of rain during the winter, and wood will start to rot very quickly if it's not sealed. MDF absorbs that moisture in the air like a sponge. That's the only reason I seal it at all.
@@MarkLindsayCNC Yes, "unevenness" is NOW a word!! Why? Because you and I said so....it is so decreed.😆
That mdf will blow up if not sealed, especially where you live. Here too, so I wouldn't take that chance either.
Thank you for the help and advice, Mark. I appreciate it.
Glueing the spoil board. I have to help someone move so I won't make the Live Q&A. I know that as months and years go by, you will have to resurface the spoil board. Eventually, wouldn't you have to replace the slats? Do you plan on removing the t-tracks and surface the whole board down to the base level spoil board?
I should never have to replace one. When I eventually surface it down close to the tops of the t-track, I'll glue and fasten strips of 1/4 inch MDF, surface and seal that, then drive on. Should I need to remove one strip of MDF, I'll mill it out as you described.
@@MarkLindsayCNC Thank you! It's a good obvious answer that my brain didn't see somehow!
Why glue the MDF? Wouldn't screws or the ceramic nails be enough? Trying to remove the glued MDF will be a "bear".
The same as with my Gatton CNC, Steve - I should never have to replace one of the MDF strips. When I eventually surface it down close to the tops of the t-track, I'll glue and fasten strips of 1/4 inch MDF, surface and seal that, then drive on.
Do you have one of these videos for 2440cnc
Sorry but no, I do not. I've never owned a 2440 CNC.
